Can You Use a Locked iPhone?

Yes, you can use a locked iPhone to perform several basic functions. If the owner enabled certain features, you can access the camera torch, take screenshots, adjust brightness and volume, enable dark mode, night shift, and true tone. The presence of a SIM card allows you to turn on airplane mode, use Wi-Fi, Bluetooth, and cellular data. You can also see the carrier being used, notifications, emergency services contact information, and the owner's Medical ID if they have set it up. If the device is lost, you can still try to unlock it for the owner.

Additionally, you can simply use the iPhone to tell the time and date. These capabilities make an unlocked iPhone a versatile tool, though mainly for those who want to use it temporarily or need basic features.

Securing an Unlocked iPhone

From a security perspective, an unlocked iPhone is quite secure. It can be used for various non-destructive activities, such as showing off, throwing (not recommended), or using it as a paperweight. One of the most useful aspects is its ability to return a lost device to its rightful owner, which can be a moment of joy when the owner retrieves their iPhone from law enforcement or another department.

Carrier Options for an Unlocked iPhone

The latest developments in the iPhone market have introduced new unlocking options, making it easier for iPhone users to have full control over their devices. Apple began selling unlocked versions of the iPhone 5 through its online store, allowing customers to purchase at full price and take it wherever they please.

Three key options are available:

Apple's Unlocked iPhone

Apple started selling unlocked versions of the iPhone 5, specifically the GSM-LTE model for ATT and Canadian operators. This means the device will work on GSM networks globally, including ATT, T-Mobile, and others like Vodafone and Softbank. However, the device does not support LTE in the US, with ATT being the only carrier that currently offers LTE service for the iPhone 5.

Other GSM operators may provide 3G HSPA data speeds, which are sufficient for many users. It's important to check if your chosen carrier offers the necessary nano-SIM card, as some unlocked devices may require this type of SIM card.

SIM Card Providers for Unlocked iPhones

Straight Talk

Straight Talk is a mobile virtual network operator (MVNO) that uses ATT and T-Mobile's networks but at a much lower cost. For $45 a month, you get unlimited voice, SMS, and around 100 MB of data daily. The Straight Talk ATT SIM allows access to ATT's HSPA network, providing adequate data speeds.

Other ATT MVNOs like H2O Wireless and Red Pocket offer similar plans, while FreedomPop is developing a WiMAX sleeve for the iPhone 5, which will eventually provide VoIP services.

T-Mobile

T-Mobile is preparing for the unlocked iPhone market. While it currently only offers 2G on the device, it is reconfiguring its network to support 3G HSPA in 15 cities and plans to have an iPhone-friendly 3G network in the next six months. LTE will be supported by T-Mobile's network in 2013, making it an attractive option for those willing to wait.

ATT

ATT is the clear choice if you want full 3G and 4G data capabilities. Its network currently supports the iPhone 5, though it requires a nano-SIM card. Once better options emerge, you can easily switch carriers without being tied to a two-year contract.

Conclusion

An unlocked iPhone, while having limitations based on its unlocked status, can still serve a variety of useful purposes. Whether it's for basic functions or secure communication, understanding the different carrier options can help you make the most of your unlocked device. By choosing the right SIM card provider or carrier, you can ensure a seamless and enjoyable experience with your unlocked iPhone.
